I've worked with the Los Angeles Zoo for 45 years, and we have this magnificent photographer, Tad Motoyama. He takes these wonderful, wonderful animal pictures. All through the years he's given me copies of these pictures. Well, I have all these gorgeous ones, so I said, 'Tad, I want to do a book with your picture on one side.'
